Abstract

A surgical system having all of the various pneumatic control sub-systems or sub-manifolds integrally mounted on a common primary manifold. The various required control mechanisms such as valves are likewise integrally mounted to the common manifold and to the sub-manifolds. Within any or all of the sub-manifolds or primary manifolds, volumes of material not necessary for the operation of the manifold are carved or pocketed out and used to form integral accumulators for storing extra pressurized air. The volume of the accumulator can vary according to the pressurized air requirement of the particular manifold, or the overall pneumatic system.

[Fo H Ming's shoulder two skills name field; J 5 The invention relates to a surgical system, in particular to a surgical system provided with a manifold with an integral pneumatic accumulator. [Previous technology 3 fiber eve show ah ah heart 娜 na ..... ~ column long / now cut off 10 15 20 with the body tissue. For example, the steps of some ophthalmic procedures require the cutting and/or excision of a transparent and gel-like clear liquid in the back of the eye, or a vitreous, consisting of many tiny fibers that are often distributed on the retina. Therefore, the cutting or excision of the vitreous must be very strict, to avoid retinal contraction, retinal and venous age separation,: net fissure, or the most severe cut or excision of the entire retina. The conventional vitrectomy probe usually comprises an outer cutting member, a cutting member coaxially arranged and movably mounted therein, and a cutting member extending radially through the inner cutting portion near the top end U and The whole is sucked out into the open joint, and the inner s, ° glass • when the _ is closed, the _ piece and the ::::= face are cut together _ the glazed body, and the cut 玻 峨 峨 切割And was sucked out. The cutting behavior may be == completed, but pneumatically driven probes operating at higher pressures are more often introduced into the eye. In addition, in a typical ophthalmic surgical procedure, air may be 5 in the posterior chamber of 200803819 and these air must It is low pressure air (3-4 psi). When the fluid is injected into the eye at low pressure, it can take some time for the surgical procedure in this part. Therefore, in order to avoid unexpected power loss, it is necessary to accumulate some reserve pressure. Conventional art devices employ an accumulator, a receptacle or a pressure tank to store the reserve pressure. Such devices occupy a significant amount of space inside the surgical console&apos; and require pneumatic coupling to a suitable manifold. therefore

[Embodiment: J 15 As shown in Fig. 1, Fig. 2, Fig. 2, and Fig. 3, the cartridge 10 which can be used in the present invention generally includes a valve plate 12, a body η, and an outer cover 16. The valve plate 12, body 14 and outer cover 16 can each be constructed of a suitable and relatively rigid thermoplastic. The valve plate 12 includes a plurality of openings 18 and a pumping channel 2 constituting a fluid passageway for sealing the fluid by a plurality of elastomers 24. When the 20-cart wearer is held in a surgical console, a plurality of joints 26 become the joint between the cassette 10 and the surgical console 100, so that The cassette 10 has different flushing and (pneumatic) suction functions. As shown in Fig. 4, the manifold assembly 2 includes a plurality of sub-assemblies or manifolds mounted on the common 7 200803819 main manifold 210. For example, the manifold assembly 200 may include a suction manifold 220 and/or an injection/flush manifold 230 and/or a valve or clamp manifold 240. As shown in Fig. 5, each manifold 210, 220, 230, and 240 (figure 5 is a collection tube 240 of 5) is a collection of separate sets and may contain sufficient functions to implement the manifold. Necessary valves, regulators, sensors, or other embedded mechanical, electrical, or electromechanical devices such as air cylinders 245. Through the main manifold 210, the manifolds 220 and 230 are in communication with the cassette, and the clamp tube 240 controls the transmission of the message between the cassette and the patient. The main manifold 210 can be mounted on the cassette mounting portion 110 of the surgical console 100, thereby engaging the cassette 1 with the main manifold 210. The primary manifold 210 may additionally include a pump and/or a fluid level and/or flow sensor (not shown). The above structure makes the main functions of each assembly separately responsible for the specific assembly, thus making assembly, troubleshooting, and maintenance more convenient and quick. Moreover, such a structure can reduce most of the tubing and line joints used in the prior art to join different components of the sub-assembly and can simplify the overall volume of the entire assembly. As shown in Fig. 6a, the main manifold 21A includes pneumatic reservoirs 310 and 312 for storing pressurized air and generating positive pressure and back pressure, respectively. For example, in Figure 6b, the transfer tube contains the pneumatic accumulators 314 and 316 of pressurized air generated by the subtraction _ (not shown). As further shown in the figures, the clamp manifold 240 includes a plurality of valves, adjustments 8, 200803819, sensors or other embeds that are used to guide the sweet manifold 240 and that are sufficient to perform the primary function of the manifold. Mechanical, electrical or electromechanical devices, such as air passages 32 of pressurized air between air cylinders 245 and the like. The storage vulators 310, 312, 314, and 316 are merely illustrative examples, and anyone skilled in the art will recognize that similar storage devices may be included in any or all of the 5 manifolds 210, 22, 230, and 24 Inside. The reservoirs 310, 312, - 314 and 316 are integrally arranged within the manifolds 21, 22, 23 and 240 and are not used in the individual manifolds for this purpose. This configuration provides more pressurized air inventory in a lighter and more reliable way in the event of a power loss. 1〇 The above description is for illustrative and explanation purposes only. It will be apparent to those skilled in the art that the present invention may be practiced without departing from the scope and spirit of the invention.
